6-bit replacement mount for 1973 50mm Summicron

I have searched the forum but can't find anything, so please forgive this request for ancient news.

 

I have three M lenses. One is 6-bit coded and my 24mm Elmarit-M takes a standard 6 screw replacement. I have found one from HK on ebay.

 

However, my 50mm has a different screw pattern and I can't find a replacement codeable mount anywhere. Any ideas?

 

Thanks

Hi Andy, If your 50 is a Summicron 11817, it can be updated by Leica AFAIK. Otherwise, 5-holes flanges ar not easy to find out i've been told. Amazon invites clients to contact them in advance here: http://tinyurl.com/k2bbqy7. Beware that the M240 does not like much replacement mounts though and the latters don't have recessed parts for focussing generally. I would check if your original mount has such a recessed part to be sure.

Thanks LCT. The mount that will come from HK only cost <$20, so it's not the end of the world if it doesn't work.

 

The one on the 1973 50mm doesn't have the groove that your example on the left shows.

 

I only want to code the 50 for EXIF purposes, as I know that the vignette adjustments in-camera are only really needed for wider than 35s.

My problem with non-coded lenses is that I identify them manually in the menu, and then change the lens for a coded lens and forget to reset the menu to "auto".  My Tele-Elmarit 90mm is not coded, but my Elmar-M 24mm is.  So I shoot with the Elmar-M and the camera thinks that I still have the Tele-Elmarit.  Drives me crazy!

I've never found a replacement flange that actually fits my '69 11817, but the coding I put on with the M-coder still works fine, even though one screw is in the codign area. I coded it a few years ago and it hasn't worn off.
